| 中文摘要: |
| 山东烟台地区是我国苹果和桃的重要产区。本研究利用性诱剂诱捕器和黄色粘虫板调查烟台地区果园中主要害虫和其他常见害虫及天敌昆虫的发生动态。结果表明:山东烟台地区苹果园和桃园中主要害虫—梨小食心虫、桃小食心虫、小绿叶蝉在两个果园中的年发生总量存在一定差异, 苹果园桃小食心虫年诱捕量为545.8头/诱捕器, 显著高于桃园年诱捕量291.4头/诱捕器;苹果园小绿叶蝉年诱捕量为94头/黄板, 显著低于桃园年诱捕量220头/黄板;两种果园中梨小食心虫年发生总量无显著差异。苹小卷叶蛾整体发生量不大。两个果园中主要天敌昆虫发生量差异较大, 桃园中黑带食蚜蝇和中华通草蛉年诱捕量分别为36.4头/黄板和41.2头/黄板, 均显著高于苹果园年诱捕量2头/黄板和4头/黄板。通过调查两种果园主要害虫与天敌昆虫的发生动态, 为果园害虫的可持续防控提供了科学依据。 |
| 英文摘要: |
| Yantai of Shandong province is an important producing area of apples and peaches in China. In this study, the occurrence dynamics of major insect pests, other common pests and natural enemy insects in orchards were investigated using sex pheromone traps and yellow sheets. The results showed that the main pests were Grapholita molesta, Carposina sasakii and Empoasca flavescens in apple orchard and peach orchard, and there was a certain difference in the total annual occurrence of the main pests. The annual trapping amount of C. sasakii in apple orchard was 545.8 individuals per trap, significantly higher than that in peach orchard (291.4 individuals per trap). The annual trapping amount of E. flavescens in apple orchard was 94 individuals per yellow sheet, significantly lower than that of 220 individuals per yellow sheet in peach orchard, while there was no significant difference in the total occurrence of G.molesta between the two orchards. A little occurrence of Adoxophyes orana was found. There was a large difference in the occurrence of major natural enemy insects between the two orchards. The annual trapping amounts of Episyrphus balteatus and Chrysoperla sinica in peach orchards were 36.4 individuals per yellow sheet and 41.2 individuals per yellow sheet, respectively, significantly higher than those in apple orchards, two individuals per yellow sheet and four individuals yellow sheet. The investigation results of occurrence dynamics of main pests and natural enemy insects in two orchards provided scientific basis for the sustainable control of orchard pests. |
